    Abstract: System and method for minimizing data bottlenecks in Low Data Rate Networks (LDRNs) that communicate facsimile transmissions. An LDRN is a facsimile network having a transmission data rate less than the data rate of the FAX machines serviced by the network. The system and method can be implemented in any type of LDRN, including analog and digital wired LDRNs, as well as analog and digital wireless (e.g., cellular) LDRNs. The system and method involve processing the facsimile transmissions in order to make the data rates of the LDRN and the FAX machines compatible, thereby minimizing any potential facsimile data bottlenecks that may occur in the LDRN due to its slower data rate.

    Abstract: An image transmission apparatus includes a color codec section for performing color image coding of a color image, a run-length codec section for performing run-length coding of a monochrome image, and a switching unit for arbitrarily switching the codec sections and to perform coding in units of pages in one communication cycle depending on whether each page is a color image or a monochrome image. Whether each page is constituted by a color image or a monochrome image is set in advance, and corresponding information is stored in a memory. Coding is performed by a coding scheme set for each page, and the coded data is transmitted. Alternatively, coded data obtained by both the codec sections and are stored in a hard disk, and the data coded by a coding scheme which an apparatus at the other end of a communication line can handle is read out and transmitted.

    Abstract: An image communication apparatus for receiving image data includes a first detector for detecting a first line synchronizing signal for one-dimensional codes in the received image data and a second detector for detecting a second line synchronizing signal for two-dimensional codes in the received image data. The apparatus counts the number of detected second line synchronizing signals in accordance with a detection by said first detector, and determines a quality of the received image data in accordance with that number of the second line synchronizing signals. In particular, the apparatus counts the number of the second line synchronizing signals detected between one first line synchronizing signal and a next first line synchronizing signal.

    Abstract: An apparatus for decoding a coded image into a pixel image and printing the pixel image at an essentially constant speed without using decoding means which decodes the coded image faster than a printing speed and pixel memory means for storing at least one page of pixel information. Decoding amount calculation means for calculating the decoding amount of the code to be decoded is provided, and compare means monitors whether the decoding amount exceeds the printing amount of the pixels to be printed and the code is converted to other code depending on the comparison result. The decoding means needs only receive the converted code from the code memory means and decode it to the pixel information. Thus, the constant speed printing apparatus is attained without high speed decoding means and one-page memory.

    Abstract: Facsimile data signal trains are transmitted from an originating station of Group 2 or Group 3 to a destination station Group 2 or Group 3 by way of an intermediate station. The scan line frequency of the facsimile data signal trains of the second group thereby amounts to n lines/second and m picture elements/line of the originals scanned whose information content is to be transmitted by facsimile data signal trains of Group 3. In the intermediate station, data signal trains of Group 2 are converted into data signal trains of Group 3 before intermediate storage and are subsequently intermediately stored, whereas data signal trains of Group 3 are intermediately stored without conversion. The data signal trains of Group 2 received in the intermediate station are converted into data signal trains of Group 3 before they are intermediately stored by demodulation, scanning with a frequency T2=m.times.n Hertz and coding of the samples according to a redundancy-reducing source code method.
